MC username not linking to stats page

So I was looking at my friend’s stats on the Wynncraft stats page, and went to viewing our guild. My own username has remained as my previous one (TheEntity_YT) and has not updated to my current MC username (Iterrion). When I click my character, it come up with an error, saying something along the lines of no player found. However, when I look up my current username, all my stats appear, and it even says I am not currently in a guild, despite being the owner of one. Anyone know the issue or a fix?
